Patent EP-0212661-A2 (EP)
Inventor: SCHREURS EMILE
IPC: H01H9/44
Filed: 1986-08-26
Abstract: A current limiter comprising a contact means (1) having at least two cooperating contacts (11, 12), at least one of which (12) being movable, connecting members (15, 16) for connecting the current limiter into a circuit, and at least one pair of preferably parallel, resistive runner rails (21, 22) arranged adjacent to the contact means, said runner rails being arranged so that the arc (4) which occurs upon contact opening in case of a short-circuit, is moved away from the contact means with the foot points of the arc running along said rails (21, 22), thereby increasing the resistance in the circuit. According to the invention each runner rail (21,22) is made of a relatively thin, insulated tape (24) of an electrically conductive material, which tape is continuously folded to form a solid resistance package. Those surfaces of the two runner rails which confront each other are at least partially uninsulated in order to form running paths for the foot points of the arc. Between the two runner rails there extend two parallel walls (32) of insulating material, which form between them a narrow gap for the arc. The magnetic field in the gap can be reinforced with the aid of a magnetic core and/or current loops.

Abstract: The hyaluronidase, which is a hyaluronic acid-specific endo-B-glucuronidase, having a molecular weight of about 28,500 in non-reduced form, is derived from buffalo leeches (that is, leeches of the sub-family Hirudinariinae, such as the species Hirudinaria manillensis or Poecilobdella granulosa) 
     The hyaluronidase, which cleaves hyaluronic acid, but not chondroitin, chondroitin -4- sulphate, chondroitin -6- sulphate or heparin, is considerably more stable at high temperatures and extremes of pH than known leech hyaluronidase. It has a wide range of uses where breakdown of hyaluronic acid is required; of particular interest is in pharmaceutical or veterinary formulations, either as an active agent or a spreading or percutaneous factor. The hyaluronidase is useful for stimulating flow of physiological fluids in the eye (for example, in the treatment of glaucoma).

Abstract: A typewriter having an automatic erasing function, having an erasing device responsive to an erasure-start key for effecting an erasing operation to successively erase the characters printed by a printing device and a controller responsive to the erasure-stop key, for permitting the erasing device to interrupt the erasing operation. The typewriter has an input buffer for storing input data which is entered through a keyboard while the erasing device is operated on the typewriter. The typewriter may be arranged so that the input buffer is cleared upon operation of an erasure-stop key. The above arrangement may be adapted to erase successive words on a display device. In this case, a device may be provided to suspend a continuous erasing operation for a predetermined time each time space data representatative of a space between the words has been detected after at least one character has been erased. This arrangement provides a time allowing an operator to depress the erasure-stop key after the erasing operation has been started.

Abstract: A lead-sealable housing, especially for use as a variable peripheral unit, for example equipped as a printer, data memory module with or without a control keyboard (38), for connection to a taxi meter, is described. The housing is composed of a housing top part (1) and of a housing bottom part (2) which serve for receiving the electronic units and which are protected by means of lead-sealable screws (3, 4). Because a paper storage shaft (11) is formed integrally in the housing top part (1), access to the electronic units remains closed. A combination of lids (12, 16) firmly connectable to the housing top part (1) or of a cover (19) and/or of a cover plate (40) makes it possible to obtain a universal modification of the equipment housing designs. <IMAGE>
